| CVE-2026-46433 | 2 Lldpd, Lldpd Project | 2 Lldpd, Lldpd | 2026-06-11 | 6.5 Medium |
| lldpd is an implementation of IEEE 802.1ab (LLDP). Prior to version 1.0.22, lldpd_decode() in src/daemon/lldpd.c strips 802.1Q VLAN tags from received Ethernet frames by calling memmove() to shift the frame payload 4 bytes left. The third argument (byte count) is s - 2 * ETHER_ADDR_LEN but should be s - 2 * ETHER_ADDR_LEN - 4, causing a 4-byte heap buffer over-read past the malloc(h_mtu) allocation when the received frame size equals the interface MTU. This issue has been patched in version 1.0.22. | ||||
| CVE-2020-27827 | 5 Fedoraproject, Lldpd Project, Openvswitch and 2 more | 28 Fedora, Lldpd, Openvswitch and 25 more | 2025-12-03 | 7.5 High |
| A flaw was found in multiple versions of OpenvSwitch. Specially crafted LLDP packets can cause memory to be lost when allocating data to handle specific optional TLVs, potentially causing a denial of service. The highest threat from this vulnerability is to system availability. | ||||
| CVE-2021-43612 | 3 Fedoraproject, Lldpd Project, Redhat | 3 Fedora, Lldpd, Enterprise Linux | 2025-02-13 | 7.5 High |
| In lldpd before 1.0.13, when decoding SONMP packets in the sonmp_decode function, it's possible to trigger an out-of-bounds heap read via short SONMP packets. | ||||
| CVE-2023-41910 | 2 Lldpd Project, Redhat | 2 Lldpd, Enterprise Linux | 2024-11-21 | 9.8 Critical |
| An issue was discovered in lldpd before 1.0.17. By crafting a CDP PDU packet with specific CDP_TLV_ADDRESSES TLVs, a malicious actor can remotely force the lldpd daemon to perform an out-of-bounds read on heap memory. This occurs in cdp_decode in daemon/protocols/cdp.c. | ||||
| CVE-2015-8012 | 1 Lldpd Project | 1 Lldpd | 2024-11-21 | 7.5 High |
| lldpd before 0.8.0 allows remote attackers to cause a denial of service (assertion failure and daemon crash) via a malformed packet. | ||||
| CVE-2015-8011 | 4 Debian, Fedoraproject, Lldpd Project and 1 more | 8 Debian Linux, Fedora, Lldpd and 5 more | 2024-11-21 | 9.8 Critical |
| Buffer overflow in the lldp_decode function in daemon/protocols/lldp.c in lldpd before 0.8.0 allows remote attackers to cause a denial of service (daemon crash) and possibly execute arbitrary code via vectors involving large management addresses and TLV boundaries. | ||||
